[SECONDARY FEATURE] API Down Notification

[GuyWhoCode]

User Story

As a student, I want to know when the extension isn't working so I know when to kindly yell at the developers to fix the issue.

Technical Tasks

• Have an Error message popup when the API doesn't load correctly (CORS issue, getting a different HTTP status code apart from 200)
• Error message should be dismissible
• Look into MUI Alerts

Acceptance Criteria

• Alert pops up when the API does not work.
